On-prem bare-metal servers without public IPs or internet access need access to Cloud Storage. Follow Google-recommended practices. What should you do?

The correct solution leverages Private Google Access for on-premises hosts, allowing private connectivity to Google APIs and services like Cloud Storage without requiring public IP addresses or internet access for the bare-metal servers. Establishing a VPN or Interconnect tunnel connects the on-premises network to a Google Cloud VPC. Advertising the 199.36.153.4/30 IP range (which is the restricted.googleapis.com VIP) via Cloud Router directs traffic for Google APIs over this private tunnel. Finally, configuring on-premises DNS to resolve .googleapis.com to restricted.googleapis.com ensures that requests from the bare-metal servers are routed to the private endpoint. The first incorrect option is wrong because it requires public IP addresses and direct internet access, which contradicts the problem statement's constraints. The second option is overly complex and introduces a single point of failure and management overhead with a proxy VM. The third option involves migrating the servers, which is not a solution for providing access from on-premises servers, and an internal load balancer cannot directly use storage.googleapis.com as a backend.
